Trace integrates the chosen tracing software (3rd-party provider LTTNg) into the rest of the Ericsson architecture (or component offering), making it available to software developers working with the Ericsson software stack, and simplifying deployment and activation for developers, users and operators. The resulting traces are extremely lightweight, and provide cluster-wide visibility of application events and operations in a production setting.
LM ensures license control of Ericsson applications at customer sites, integrated with both in-house and third-party backends (i.e. Sentinel RMS, Cloud).
Duties:
- development of new features, maintain existing,
- ensuring stability of test jobs,
- observing and maintaining performance, in particular under saturated or overloaded conditions (CPU, memory, network, IO).
Contributions:
- refactoring build, packaging and deployment scripts
- partitioning the software to isolate the new licensing back-end from the rest of the product.
- develop and integrate a new back-end (Sentinel Cloud) into the licensing infrastructure
Technical environment:
- Linux: LDE (Linux Distribution Extension), LOTC (Linux Open Telecom Cluster), SLES (SUSE Linux Enterprise Server), OpenSuse, DRBD
- C++, Java, Linux tool suite (bash, gmake, cmake, autotools, python, perl, awk, sed, RPM, etc),
- Build pipeline: Jenkins (continuous integration), Gerrit (code review), JIRA (issue and project tracking)
- C++: OpenSAF (high-availability framework), LTTNg, Poco, MAF (Middleware-Agnostic Framework), gtest, gmock
- licensing: Sentinel RMS, Sentinel Cloud
- Overload testing: perf, sar, stress, Linux Performance Observability Tools, Trace Compass
- Additional context: clustering, availability/resilience, distributed systems
- hardware: GEP-3, GEP-5 (multi-core, Xeon-based, Generic Ericsson Processor blades), Xen virtualisation

Maintenance and development of the (Gigaspace) cache support system (market data + static data) :
- Incorporation of new fields and structures into cache schema, and supporting changes in the code (C++, Java, C#), ensuring backwards and forward compatibility
- Maintenance and evolution of the changes to configuration management. i.e. compile Gigaspace in debug mode, allowing for the deployment into the developer environment (and ensuring symmetry between developer, testing and production environments)
- Deployment of cache proxy onto testing and development compute grids
- Production debugging (remote desktop, remote debug, WMI, Powershell) + crash dump capture and analysis
- Study and use of surveillance applications, grid management, and distributed computation frameworks (internal and OTS)

- Developer support
Development of a C++ LoadService (specialized DB front-end service) :
- Development of a generic “access module” (to hide the details of our use of Google protobuf packets and library)
- Census of all target database (common market and static data) entry points and conversion to new LoadService interface
- Connection management and optimization (socket lifecycle)
- Adaptation of LoadService to a second target DB, and extending the flexibility of the protocol and the supported types (i.e. input vectors)
- Migration of hardcoded SQL queries to stored procedures
- Massive legacy code refactoring. Suppression of 150 KLOC (over 1.5 MLOC initial)
- Support, diagnoses, bug management
- Validation of results (DB queries) through instrumentation of access functions (and use of Boost serialization to produce reports)
- Reconciliation of divergent reports
- Unit and performance tests
- Developer support
- Results : impact on database divided by 5
